Cap't I would just go with a cylinder head rebuild seeing as how the cross hatching is still visible and leave the lower end as is except for probably installing a new timing chain, guides and probably an oil pump and oil pump chain. If you need any help with anything just let me know. I am in the area every now and then visiting my parents who live nearby. In my opinion, the best automotive machine shop in the area (Macon) is Cassidy. They currently have my block, crank, pistons and connecting rods from the 240D. They allow you to supply the parts - especially on the MB's. I would recommend them for a complete cyl head rebuild.
